Abstract

Continuous-wave CO2 laser-photosensitized (SF6) decomposition of 4-silaspiro [3, 3] heptane is dominated by the transient formation and polymerization of 2-silaallene. The first experimental evidence for 2-silaallene has been achieved via scavenging with alcohols ROH (R CH3, CF3CH2) to afford dialkoxy (dimethyl) silanes,(RO) 2Si (CH3) 2. ESCA analysis of the polymer demonstrates SiC2 stoichiometry and indicates the incorporation ...
